The Connectivity Standards Alliance (Alliance) released the Aliro 1.0 specification, a new communication protocol and credential standard designed to revolutionize how users interact with access points in every aspect of their lives. Aliro is built for broader impact, aiming to streamline interoperability across varied access control use cases, including corporate offices, universities, hospitality venues and single and multi-family residential homes.

Aliro received confirmed commitment from popular mobile wallet ecosystems. By aligning with Apple, Google and Samsung, Aliro aims to offer a standardized digital credential experience leveraging the smartphones and wearables people use every day.

“It’s a unique moment, to have all of the wallet providers caring about access control and all committed to something,” said Nelson Henry, vice president, security technology and engineering, Last Lock, who serves as the Aliro steering committee chairperson for the Alliance. This strategic collaboration expands adoption pathways, empowering users to move easily between homes, workplaces and public spaces using the secure digital wallets native to their operating systems.

“Aliro is solving the fragmentation that has held back digital key adoption, replacing it with a single interoperability standard built through Alliance Member collaboration,” said Tobin Richardson, president and CEO, Connectivity Standards Alliance. “By connecting the access control industry directly to leading mobile wallet ecosystems, it delivers a secure, frictionless experience that goes well beyond the front door. Lower integration complexity means faster innovation and shorter time to market. This is how the future of access control gets built.”

The Aliro 1.0 specification establishes a robust framework utilizing asymmetric cryptography to ensure secured and trusted interactions between user devices and readers, while respecting user privacy. This standardized protocol is designed for broad application across the entire access control ecosystem, providing a reliable experience in corporate offices, universities, hospitality venues, single and multi-family homes and even areas without network coverage, such as underground parking garages and elevators.

“What makes a good standard is open transparency, clear focus and doing that with good boundaries correctly,” Henry said. “That makes for a world where people can build well, and they can layer on top. We should be a good partner with other standards. It should be easy to build on top of us and then go do what’s appropriate for your use case.”

To meet diverse installation requirements, the specification supports a variety of transport technologies, including Near Field Communication (NFC) for tap-to-access, Bluetooth Low Energy (Bluetooth LE) for user-initiated long-range communication and Bluetooth LE plus Ultra-Wideband (UWB) for a secured hands-free authentication method. To ensure global reliability, Aliro includes a comprehensive certification program and supporting test suites managed through Authorized Test Labs. 

“Aliro, fundamentally, is aiming to be the standardization of how your smart device acts as a digital key to locks readers,” Henry summarized. “It’s a credentialing standard that’s really focused on smart devices and how we make an open baseline for what it looks like to do that credentialing interaction. It is consciously agnostic to what the backend solution is.”

It was important and intentional for the Alliance to make Aliro agnostic to whichever backend linking a solution uses — OSDP, Wi-Fi, etc. — and to the administrative model of setting up each device. “From a stack perspective, it’s made to work with different approaches because all the markets have their own ways in which they need to do this stuff,” Henry said. “To make a good foundation, getting the right amount of scope was really important to us.”

This initiative unifies a global collective of over 220 member companies, from lock manufacturers to silicon vendors and mobile platform leaders, working together to pave the way for a better, more secure mobile access experience. Through close collaboration, member companies (including Apple, ASSA ABLOY, Google LLC, Infineon Technologies AG, Last Lock Inc., Samsung Electronics and STMicroelectronics) pooled technologies, expertise and innovations to enable the Aliro 1.0 specification, with Apple, Allegion, Aqara, Google LLC, HID, Kastle, Kwikset, Last Lock Inc., Nordic Semiconductor, Nuki Home Solutions, NXP Semiconductors, Qorvo, Samsung Electronics and STMicroelectronics expected to be the first to achieve Aliro 1.0 certification.

This coalition is already looking toward future phases to integrate upcoming market and ecosystem requirements, such as expanded use cases like secure key sharing, while maintaining backward compatibility to ensure that current implementations are not compromised as the technology matures.

In a time where customer demand is skewing toward having everything accessible on their digital devices, standardization is driving the wheel. “Instead of having to learn every company and have a custom agreement with every company, you can start to build something that is copy and paste across companies,” Henry said. “Also, if we ever want to have stuff that is widely adopted by people who aren’t in our industry, having standardized answers helps a lot.”

For manufacturers, Aliro acts as a universal arbiter for interoperability certification. Integrators benefit from this streamlined approach through easier setup and more efficient troubleshooting across devices from multiple hardware providers. Regarding what Aliro 1.0 will change for integrators, Nelson added, “There’s a pattern of an effect.”

It starts with the practicality of deployment, rather than fundamentally changing what integrators already do. “You’ll start to have a lot more options,” Henry said. “It’ll be easier to do things, which means speed of deployment probably goes up. … You’ll be able to swap around different options and start to pick readers and devices less at a site scale and more at a door scale. If I want to pick more for the use case and less the building case, that starts to be an option. You start to get to where the credential is more agnostic than the vendor stack. … If I’m an integrator, that means I can go build more interesting things for my customers.”

Ultimately, Aliro is designed to provide system owners with simplified maintenance and the flexibility to mix and match vendor-independent hardware and software across a wide variety of user devices.
